"Show, don't tell" is a great piece of advice that, unfortunately, is massively misunderstood. People interpret the words literally and believe that "show" means to describe what everything looks like in excruciating detail – every little object in the room, every article of clothing worn by the characters, and so on. Details are great, but what "show, don't tell" really means is to show what all the scenes and actions mean, why we should care about what's going on. What readers want to be shown is how it feels to be fully immersed in the story, actually experiencing the thoughts and feelings of the character(s) as they go along. See more: Show Don't Tell
